High-efficiency energy-saving stone mill

High-efficiency energy-saving stone mill

The stone mill is a new type of machine developed by the Trapezium mill. It is a stone processing equipment mainly suitable for the ultra-fine combustion of non-inflammable and explosive brittle materials with medium and low hardness and Mohs hardness of 6. Powder processing such as limestone, calcite, chalk, dolomite, carbon black, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, barite More than 100 kinds of materials such as gypsum, the fine powder finished product can be arbitrarily adjusted between 325-3000 mesh, and the output can reach 0.7-7.5 tons per hour.

With high efficiency, energy-saving and wearing parts, long service life, high reliability, high product fineness, high environmental protection, cleanliness, etc. When the stone mill is working, the main motor drives the spindle and the turntable through the reducer, and the roller pin on the edge of the turntable drives dozens of The grinding roller rolls in the grinding ring raceway. The bulk material is broken into small particles by a hammer crusher and then sent to the storage bin by the hoist, and then passed through the vibrating feeder and the inclined feeding pipe to uniformly feed the material to the bulk disc of the upper part of the turntable. The material is scattered to the circumference of the circle under the action of centrifugal force, and falls into the raceway of the grinding ring, which is impacted, rolled and ground by the ring roller, processed into a powder through the processing of the three-layer loop, and the high-pressure fan passes the external air through suction. Inhaled into the machine and the pulverized material is brought into the classifier. The impeller rotating inside the classifier re-grinds the coarse material, and the fine powder that meets the requirements enters the cyclone dust collector with the airflow and is discharged from the lower discharge valve, and the airflow with a small amount of fine dust passes. The pulse dust collector is cleaned and discharged through a fan and muffler

The assembly requirements for the grinding roller bearing of the stone mill are relatively strict. The enterprise generally assembles the bearing by cooling it in dry ice. Once there is a gap between the bearing and the bearing chamber, it will affect the normal operation of the bearing, causing the bearing to heat up, which will cause the bearing to burn. Fushi Blue technology is fast, easy to operate and can be repaired on site in many cases.
